Getting started

git clone --recursive https://github.com/mapsforge/vtm

Install Android SDK and build-tools 20.0. From extras add 'Android Support Library/Repository' and 'Google Repository'. The commands below should set things up correctly when Android SDK is already installed.

export ANDROID_HOME=/path/to/your/android-sdk
./android-stuff.sh

Eclipse

./gradlew eclipse
Import all 'vtm' sub-projects into Eclipse.

Android-Studio

Just import build.gradle

Gradle

You can run gradle tasks directly (see also ./gradlew -q tasks):
./gradlew clean install
to build the libraries and add them to the local maven repository.
./gradlew :vtm-android-example:run
to run the android example
./gradlew :vtm-desktop:run
to run the desktop demo (only Linux64 and Win64 native libs are provided atm)
./gradlew :vtm-web-app:jettyDraftWar
to run the webgl demo
